I would very much like to help you in your endeavor but some of what you need I am not familiar with and a picture of your aquarium might be of some help also.
In this post I am also asking for some additional information (but I am trying to not overwhelm you with this request).

Thanks, I purchased a corner type unit (was used and it only had coral in it, will need to give it a good cleaning.
Might I suggest that after you have everything you believe to clean that you clean again with a mild chlorine solution for final disinfection.

... 100G with 4' twin flouresant lights. It is more triangular in area then it is in height.
If you are contemplating live plants in your tank (which I have for the extreme aesthetics which they provide) then
1) Please look on the bulbs and the ballast for descriptions including one which will be a number followed by the letter K and post your findings.
2) Your next decision will be "what you will put" in the bottom of your tank. I have laterite and gravel and a laminate thereof but many folks use a colored natural gravel or artificial gravel with tab fertilizers.

Yes and the following two threads may be of some help

I assume will need a ... filter (looking at the new fluval, any good or should I look for something else???) ...
The two most common types of filtration equipment are HOB (Hang on Back) and cannister. [Biowheels are also becoming popular but are probably not feasible for your corner aquarium).
Another type of filtration equipment is termed wet/dry. IMHO (In My Humble Opinion) the wet/dry is the best but many, many folks will disagree and this filtration equipment is not typically recommended for folks who are first time fish keepers.
As you have purchased a "corner aquarium" I assume that if is a fairly nice aquarium which you will place in a corner and which has a tank which is supported by an enclosed stand.
I therefore believe that you will want cannister filtration as the cannister will be concealed by the enclosed stand.
My system is wet/dry but I do have very, very limited experience with cannister filtration which I employed for a brief period as tertiary filtration.
The filter which I used was an Eheim and I had good luck with it.
The following threads may be of some help in your procurement decision.

Please note that many members of this forum believe that the actual filtration provided by a cannister filter is approximately 50% to 75% of the rated filtration.

... and will I need some sort of aerator like a power head or just one that blows bubbles?
The following is a recent thread concerning aeration.

Pet store said some fish don't like the current powerheads produce ...
Yes but some fish do (ie. Plecos).
The procurement determination of a powerhead should be based on the fish which you will ultimately stock.
Please post additional questions based on this post.
Also was the link to tank cycling beneficial?
You will be perfoming 25% weekly WC's (Water Changes) during and subsequent to cycling. You might consider this factor in the placement of your aquarium.
